Freezing ovarian tissue in childhood to restore fertility in Turner syndrome

This Danish research study is testing a groundbreaking idea: that girls diagnosed with Turner syndrome can preserve their ability to have biological children by having one ovary surgically removed and frozen during childhood. Years later, as adults, the frozen ovary tissue could be transplanted back into the body, potentially allowing them to become pregnant using their own eggs. The study aims to enroll 100 girls aged 2–17 to see if this approach works safely and effectively.

Turner syndrome typically causes girls to lose their egg-producing cells very early in life, making pregnancy with their own biological eggs extremely difficult or impossible. This trial exists because many girls and women with Turner syndrome experience infertility as one of the most distressing aspects of their condition, and current treatments don't reliably restore the ability to have biological children. The researchers hope that preserving ovarian tissue before it's lost could offer a real path to parenthood.
